    BSOD fastfat.sys, vwifibus.sys, swipsec.sys, others


    Repeated BSODs, usually with different driver each time. Driver IRQ Less than or equal to.
    Other than SWIPsec.sys (Sonicwall VPN?), they are usually windows drivers.Attachment 67025

    Hi nckestrel,

    Welcome to the 8forums.

    You're correct, it is Sonicwall.
    I guess you know what the next step is?
    Driver Reference Table - SWIPsec.sys
    Code:
    1: kd> lmvm SWIPsec
    start             end                 module name
    fffff800`85d64000 fffff800`85d81000   SWIPsec  T (no symbols)           
        Loaded symbol image file: SWIPsec.sys
        Image path: \??\C:\WINDOWS\system32\Drivers\SWIPsec.sys
        Image name: SWIPsec.sys

    Are you using more software like SonicWall?
    Driver Reference Table - dnelwf64.sys
    Code:
    ffffd000`c29c51a8  fffff800`839cb0a3Unable to load image \SystemRoot\system32\DRIVERS\dnelwf64.sys, Win32 error 0n2

    Thanks.
    So the other BSODs (vwifibus.sys, fastest.sys, etc) are due to the Sonicwall? Or just the SWIPsec.sys one? There's been about a dozen in the past month or two, and only one or two have mentioned SWIPsec.sys.
    I did uninstall and reinstall the Sonicwall VPN today. But I'm not sure that will stop them.

    Driver Reference Table - dlkmd.sys
